Galil / Re: Mach 3 - Galil DMC 4030 - Proma THC - No THC action
« on: October 21, 2019, 10:08:47 PM »I probably will not be any help to you but I too have a Proma THC and a home made plasma table. I am using mach4 and going through a PMDX-416 to the proma and from the proma to the stepper controller. With it wired like the drawing shows in the Proma manual I have control of the Z axis when the torch is off and the Proma is powered up. When the torch is on the Proma moves the Z axis and the cnc (mcah4) does not know the actual position of the Z axis. I guess that is about as controlled as I am going to get. I also have tried the Proma set up as a standalone device outputting to the z axis and it controls that way also. Of course when the Proma is wired for stand alone I can never move the z axis from the cnc.
Are you using the Proma THC-SD then? I may look into that and see if there is a way to pass control back and forth to the THC with a relay and another output. I need Z control to zero before the cut.
